THERMODYNAMIC PROPERTIES OF ORGANIC-COMPOUNDS .2. COMBUSTION AND SUBLIMATION ENTHALPIES OF 2,4,6-TRIMETHYLBENZONITRILE N-OXIDE

Experimental vapor pressures and enthalpy of combustion are reported for 2,4,6-trimethylbenzonitrile N-oxide, along with the enthalpy of sublimation derived from the temperature dependence of the vapor pressure. Results of these measurements are used to compute standard enthalpies of formation in the crystalline and gaseous states, DELTA(f)H(m)-degrees-(cr) = 49.25 +/- 3.54 kJ.mol-1 and DELTA(f)H(m)-degrees-(g) = 137.0 +/- 4.0 kJ.mol-1, respectively.
